Don't, it's stressful. Playing the game isn't enough either. You have to understand the game , watch replays, overall have an outstanding work ethic. Also as Executionerken pointed out, even if you manage to do all of this and are good enough, you're only going to have a CHANCE at going pro, it's not a guarantee.

Reignover in EU, and Move/Rush in NA. High solo Q is hard to say, as they are teamless and I don't know how they would work in a team enviornment.
Hard to say. Players who don't make NACS lack discipline/work ethic/have attitude
I would love to answer this during off-season!
MoonJNG is on his way to be one of the best junglers in NA, I think mashme is playing well right now as well
Literally be yourself. Let your personality run rampant. When I streamed , it was the most relaxing easy going job ever. Also think of your viewers as friends, because thats ultimately what they turn into.
